MACHINE FOR FORMING HARiNESS-LOOPS.

SPECIFICATION forming part of Letters Patent No. 366,024, dated July 5, 18h37.4

l Application filed April 20, 188i. Serial No. 235,448. (No model.) 1

. Forming and Stamping Loops, of which the following is a specitication.

The object of my invention is to improve the present machinery by which harness-loops are made; and it consists of the combination of devices for taking up the loose leather, forming and embossing the loop free from wrinkles, all of which will be described below, and pointed out in the claims.

In the accompanying drawings, forming part of this specification, similar letters indi-i cate corresponding parts throughout the various views, of which- Figure l is a front elevation of my improved machine. Fig. 2 is a sectional plan of same. Fig. 3 is an enlarged sectional elevation of the dies and some of their operative parts, and Fig. 4 isan enlarged View of a sliding wedge, by which the die which bears upon the top of a loop is moved upward.

A is the machine-bed, and B B are blocks, within which are rigidlysecured suitable nuts, C C, to which are threaded the horizontal serew-shafts D D. Columns E E rise from the blocks B B at either end of said bed and support a cap-piece, F, all being held in place upon said bed A by means of bolts G and nuts q. A vertical screwshatt, H, passes through the cap-piece F at I, and carries at its upper end a lever, J. A follower, K, is swiveled to the lower end of said screw-shaft H, and is guided in its vertical movement by tongues e, formed upon the columns E, and by guiderods L, carried upon the follower and passing upward into the eap-piece F. The screws D D, which are provided, one with a right and Y the other with a left thread, have a smooth near their farther end, with a boss, s, to which is bolted a lever-spring, s. These springs bear with great forceupon end blocks, U U, and by reason of their chamfercd sides the pressure of said springs increases with the inward movement of the said screws D D.

V is the bed-die, which is looselyr tenoned at either end into the end blocks, UU. (Seen in Fig. l.)

The surfaces ofthe dies T V which come in contact with a loop may be engraved for ornameutation, as desired. I

Pressure-blocks of ,the desired width and length may be placed at the under side of the follower K, and secured thereto by reason o f the ears 7c and screws 7c'.

W is a sliding wedge, which is adapted to move transversely upon the bed A, or within a groove, a, formed for the purpose. This is provided with a threaded portion, w, to which is threaded the lscrew-shaft fw', carried in a bearing, WV. and having upon its outer end a spur-gear, X, meshing with the spur-gear X', mounted at one end of ashaft, Y, and. by means of the crank 1/ at the opposite end motion is communicated to the said wedge W. The beddie V is supported by'this wedge W', the object being to render said die easily adjustable and independent of the others.

The operation of the machine when forming a loop is as follows, to wit: A loop is placed between the dies T T, strap side or bottom side up. Then the said dies are moved onto the loop by aid of the blocks S S and the screws D D with considerable pressure. The said dies T T are adj ustably supported by means of the springs S', which are conveniently connected to the blocks S at s?, and whose outer ends enter the sockets t, formed in the dies T. These may be set as desired by aid ofthe set-screws t', threaded to ears projecting from the blocks roo S for this purpose. The next` movement is preferably to put pressure onto the loop from below by causing the wedge W to advance under thedieVsufcient to straighten ont the loose leather, when, after applying pressure from above by thc screw H, the nal pressure may be given to the die V, as before.

Having described myinvention,wh at claim, and desire to secure by Letters Patent, is

l. In a press for forming harness-loops, the combination of the dies T V, their operating mechanism, the end blocks, U, and mechanism, substantially as shown, whereby' the die V may be raised as desired, for the purpose set forth.

2. 'ln a press for forming harnessloops, the combination, with the die V, of the adjustable suspended dies T and their operating niechanism, substantially asand for the purpose explained.

3. The combination of a longitudinally-beveled slide, the machinebed provided with a transverse groove, int-o which said slide is f1tted, the die V, the adjustable suspended dies T, and mechanism, substantially as described, for moving said slide across said bed, for the purpose explained.

4. The combination, with the dies T', having sockets t, and blocks S, having ears to which are threaded screws t', of springs S', constructed and operating substantiallyfor the purpose set forth.

5. Thecombination of the beddie, the adjustable suspended dies, alongitudinally-beveled slide, the machine-bed having a transverse groove, into which said slide is fitted, a screw-shaft threaded to a portion of said slide, and operating mechanism whereby said screwshaft is rotated, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.-

CHARLES PELISSIER.
